I know my glow plug relay is bad in my '83 240d...... I've got one on order, and in the mean time, I pull the relay module out from it's case and use a plastic spring clamp to MAKE the relay contact and she starts right up......

My question is has anyone (besides me) ever pulled the wires out of the 4-wire control connector (in the course of troubleshooting) and accidentlly touched the violet wire to the black/red wire? It turns the starter over!!!! I had the key on, and never tried it with the key out, but I was pretty impressed........ If you hold them together long enough, it'll start................

man.......it's past my bedtime.
